My girlfreind and I where traveling north on Rt. 89. She was driving. I noticed what at first I thought was a star but it was mid day and I then realized it was an object, probably a plane but to far away to tell. It was directly above the highway in front of us and the sun was above it and to the right. It seemed to be greatly reflecting the sun. I pulled my video camera out so I could use the zoom to see what it was and as I turned the camera on it vanished into thin air. Now you see it, now you don't. I was very upset that I did not get it on video but it never gave me the chance.
